Gelcoat – Black

Gelcoat can be colored prior to adding catalyst. Color pigment available for purchase.

GEL TIME DEPENDS ON AMOUNT OF CATALYST MIXED Adjust the catalyst level to slow down or speed up gel time. Cooler temperatures may require a higher percentage of catalyst than warmer temperature conditions. Proper catalyzation is imperative for proper cure when using polyester. The higher the percentage of hardener, the faster the gelcoat will dry. Do not add less than 1% catalyst or greater than 3% catalyst. We recommend a trial batch to determine final catalyst ratio.
